My invention relates to a waste connection and I declare the following to be afull, clear,concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the sam'e, reference beinghad to the accompanying drawing in which like reference characters refer to like parts throughout the specification.

' do his own plumbing so far as the'waste line and soil line pipes are concerned.

I-Ieretoforethe stoppage in'the wastelineusually. occurred at the connection of the wasteline with the soil line or hub of the soil pipe. With the present invention this stoppage can be easily and quickly remedied by the owner of the building without the aidofa plumber orjskilled mechanic .by merely loosening. certain .bolts employed .in the connection and separating waste i line pipe from the hub ofthesoil. pipe and then reassembling the parts, which are, so vmade that they are bound to fit togetherperfectly no matter who does the work.

Thus the connection may seryegas a cleanout ,of the waste and, soil lines .whensaid lines, are

stopped bylint orother foreignmatter,

"The object .will be understood by referring to the drawingqinwhich. l

Fig- 1 is an elevational view of'l the device.

Fig. 2 is a central vertical section.

. Fig.3 is a detail enlarged View showing a perspective of a'tunnel member employed.

Fig. 4 is a detail enlarged View showing a headed bolt employed.

Fig. 5 is a detail enlarged view of another head bolt employed showing its relation to one of its cooperating parts. 1

Fig. 6 is a detail enlarged view showing a. modifled form of the tunnel member employed, parts broken away.

Referring more particularly to the drawing the device embodies a hub member I having a flange 2 on its upper rim. The lower portion of hub I is formed with a conical surface at 3, whereby to converge towards the diminished diameter portion 4 or so il pipe line of hub I.

There isdisposed withinhub I tunnel member 5-whichhas at' its top portion. a'disc or flange 6 5' formed integral therewith. An annular boss I upstandingonflange 6 is'made integral therewith, whereby to provide a surface for internal threads I hereinaftermentioned. At diametrical opposite "positions on boss/l0 are formed ridges II, II having reduced portions .at I2, I2. De-

ending members 15, I are fmade integral with the'ends of portions I2, I2. 'Apertures IE, IS are made in said portions I2, IZLfor-Ithe projection, of bolts 2B, 29 having heads.12I', j2I'. Each of said heads :EI is arc-shaped, whereby to conform to the curvature of' theouter surface of hub 2 against which they fltp Furthermore each of said heads 2I i's equipped-with n shoulder and beveled su-r-facehtit,whereby to conform to the beveled or conical surface 21 0f hub I. Nuts 30, are screw mountedto the upper ends .of bolts 26, zagwhereby'to drawsaid hub I and flange 6 towards each other in a hermetically sealed'maner when-said-p'arts are- 'a's'sembled.

Annular washer v 3| is disposed between the under surface of flange-6 and the upper surface I of'hub Lwhereby to aidinsealing the connec "tionbetween said'parts. Themeans'forholding headsiI, 2i against the 39 beveled conical surface'Z'I of hub'I. embodies adgjllstable screwbolts 32, 32'. Each of said bolts 32 is mounted inf a tr'ansverse threaded aperture made in boltzil; 'The'head 33 of each of said :bolts f3 2'abutsagainst the {inner surface of de- 33 pendingmember I 5, whereby to hold said bolt 26 withits head 2i firmly against the beveled surface 21 of hub i. Turning bolt 32 to the right or left onbolt 2E3 will take upf-any' slack between the surface ofbolt 32'and the contiguous surface of depending member I5. The head 33 of each of the bolts 32 is wedge shaped to fit into a corresponding V shaped groove 34 made on the inner surface of depending member I5, whereby to prevent said bolt .ihfrom turning when set for loosening or changing from its adjusted position. V shaped groove 34 need not be made deep but a rather shallow groove will answer the purpose just as well.

' The central portion 49 of tunnel 5 is of tubular formation. A waste line pipe 43 having ex ternal threads is screw mounted to said threads I of boss Hi. Said tube projects down through hub I at least below conical surface 3 of hub I .to eliminate the possibility of exposing a por- 53 tion of said conical surface 3, which exposed surface would form an obstruction against which grease, lint and other foreign matter might tend to catch and accumulate and finally effect a stoppage of the waste line.

The means for sealing the outer surface of the lower end of tube 40 of tunnel member with the lower portions of hub I contemplates an adjustable collar 50 held in predetermined position to tube 40 by set screw bolts 5|, 5| threaded to enlargements 52, 52 made integral with collar 50 and at diametrical opposite positions on collar 50. The lower surface of collar 50 is enlarged at 53. The under surface of enlarged part 53 is concaved at 54, whereby to fit over the annular washer or gasket 55. The under surface of gasket 55 rests against the conical surface 3 of hub I and is pressed closely thereagainst, whereby to form a hermetically sealed joint between outer surface of tube 40 of tunnel member 5 and the inner conical surface 3 of hub I.

In operation the user will first adjust collar 50 on tubular part 40 of tunnel member 5, whereby washer 55 will effect a hermetically sealed joint with conical part 3 of hub I when the parts are assembled. He will adjust also screw bolts 32 in bolts 29, 20, whereby to hold heads 2i, 2| of said bolts 20, against the annular external beveled part 21 of hub I. Washer 3! will be placed on the upper surface of flange 2 of hub I, the tunnel 40 of part 5 W111 then be inserted in hub I with tubular portion 4i] extending below conical surface 3 thereof. Bolts 2U, 20 will be projected up through apertures IE, IS in parts 12, I2 of disc or flange 6 and nuts 3i], tightening on bolts 20, 20, whereby to draw shoulders 25 of heads 2| upward against the beveled surface 21 of hub I. This will draw hub I and tunnel member 5 tightly together with washer 3I in between and washer 55 sealed against the contiguous conical surface 3 of hub I.

It will be observed that in the use of the tunnel member 5 with the hub member I, that a perfect fitting joint is effected no matter at what angle the waste pipe 43 approaches the hub I and no matter who does the work, that is, the joint is foolproof, whereas heretofore such a joint through carelessness of the workman or otherwise was not centered to hub I. This resulted in exposing a portion of the conical part 3 of hub I, whereby lint, matches and grease would catch and accumulate and finally effect a complete stoppage of the waste line.

Fig. 6 shows a modified form of tubular member 5, wherein collar 50 is made integral with tubular portion and not separate as above described.

Having thus described my mvention what I claim as new and desire to secure by Letters Patent is as follows:

1. In a waste connection, a hub having a conical surface connected with an outlet directly therebelow, a tunnel member disposed within said hub and extending below said conical surface, a flange member formed on said tunnel member, bolts connecting said flange member with said hub, a collar attached to said tunnel member, a washer disposed between said collar member and said conical surface for sealing the connection between the tunnel member and said hub to form a hermetically sealed joint.

2. In a waste connection, a hub member having a conical surface, a tunnel member mounted within said hub member and extending below said conical surface, said tunnel member having depending members with V shaped grooves for holding said second named member to said hub member and other bolts having wedge shaped heads cooperating with said V shaped grooves mounted in said first bolts, whereby to hold said first named bolts in predetermined position and a gasket for sealing the connection between said hub member and said tunnel member.

3. In a waste connection, a hub member having an interior conical surface, a tunnel member mounted within said hub member and extending below said conical surface, said tunnel member having depending members with V shaped grooves therein, bolts for holding said tunnel member to said hub member, other bolts having wedge shaped heads cooperating with said V shaped grooves for holding said first named bolts against said hub member, an adjustable collar attached to said tunnel member, a washer disposed between said collar member and said conical surface of said hub member and another washer disposed between said tunnel member and said hub member, whereby to effect a hermetically sealed joint.
